- W2003662919 abstract "With equipping multiple antennas at both transmitter and receiver ends, the desired signals in the OFDM wireless communications could be transmitted and received through multiple uncorrelated channels for achieving twofold benefits and high flexibility. For this kind of MIMO-OFDM systems, if the assistance of channel estimation is under consideration, the overall system performance is able to be further enhanced. This paper proposed a pilot-symbol-assisted channel estimation technique for MIMO architecture by assigning known pilot symbols orthogonally between different transmitting antennas. The mixed transmitted signals could be completely separated at the receiver end due to the orthogonal property of pilot blocks. Some simulation results are given to illustrate the superior overall performance that can beachieved by the proposed channel estimation algorithm in MIMO-OFDM systems under COST 207 mobile wireless environments." @default.
